250 Kh/sec? is it an old cpu? i've 4100 Khash/sec with an intel q6600 at 2.4ghz (quadcore).

The CPU probably uses noticably more power when it calculates hashes than when it's just displaying pictures or transfering data. Even though it's not very much, it's unlikely that you earn enough from hashing to cover the extra power consumption.

You're right, such a low khash/s rate is practically worthless, but I have no intention of having this computer be a Dedicated miner.  As long as it's doing a little bit now and then, I'm happy with that.  And I did switch it back to only 1 thread, after finally getting OpenCL support installed.  It is now averaging 250 khash/s, which I know is still really small, but whatever.  I want the computer to do Something rather than sit there displaying pictures, or something unproductive like that.  Mostly this computer runs P2P stuff.  So, whatever energy may be wasted on such a small amount of mining capability, is not wasted at all on the other things I have it doing.  So, it's OK with me.

In the pool terminology, you found one "share", which is only small piece in the finding of valid Bitcoin block.


I don't know miner you are using, but I expect you should set one thread per real CPU core. I doubt you have 25 core machine :-).

Also, mining with 85-100 khash/s is absolutely worthless. You probably spent much more money on electricity. With your computation power, you'll earn 50 BTC in 32511 days (yes, almost 90 years). I recommend you to turn off mining on this machine...

I don't see how that could really help me. I can search transactions, But if I found the block for the pool, The block would show as found by the pool, no?

Hello, this is the longest thread I can remember seeing, Ever.  Wow...  Uhm... I am using a screensaver to do work in the pool, the 4way one, not the other three in the package.  Once, a few days ago, I noticed it said it had found a block, I was like Cool.  I haven't seen that before, or since.  I saw on the website that I got a reward equal to about 1/3 of a bitcent.  LOL  Is there any way I can improve the khash/s processing without totally hanging my CPU?  I know people have been using GPU miners, but I don't know how I can possibly get one working with my laptop's ATI Mobility Radeon 7500.

I've tried in the past to get newer, better, drivers for my graphics card, and it always messes things up until I manage to get Windows Update to fix the problem.  So, I would really rather not go searching around the internet for what will probably just screw things up again.  Is there a way to Install OpenCL support, without having to get different drivers for my graphics card?  If I had OpenCL support already, would the screen saver miner be able to get a lot more khash/s done via the GPU and not use so many CPU threads?

Right now it is set to use 25 CPU threads, and khash/s is about 85 to 100.  If I set many more CPU threads the computer will hang and crash.

I think I may have found he solution to my problem just now, but I'm not sure yet as I'm still downloading.  According to this site, http://www.heatonresearch.com/encog/opencl/install/encog-opencl-java.html, I need AMD APP SDK to get OpenCL 1.1 support installed for my AMD/ATI video card.  But the file the AMD site told me to download is being called ATI Stream SDK, which is the old name for it, I think.  So I'm downloading ATI Stream, and hopefully I'll get the right DLLs and such.

Ok, I have good news and bad news. After installing AMD Stream SDK, and rebooting just because I thought it would help, the screensaver OpenCL miner does recognize that there is an OpenCL DLL and stuff, but the darn thing crashes every time I try it.   But the good news is that when I run the 4way miner, with just 1 CPU thread, it is getting well over 250khash/s, a massive improvement.  I don't understand how, but it is somehow processing better.  So, Yay!

As you can see on Y axis label it's "reward / time spent" (in the mining pool).

Interesting graph, but not completely clear.  Is this a plot of the total reward, or the total reward *per time spent mining in the pool*?  'cos if you can increase your reward by 3.5% and decrease the time spent mining by 5% (or whatever), then that might be a significant reward.  You could spend that free time mining elsewhere.

Maybe,

could help?

Any way to see precisely what Blocks we found? I see I found one, but There is no where on the site to show which one, and I was AFK when It found it.

Expected daily reward for current difficulty  for 340Mhas/s is 6.15 BTC, so it looks correct...

Well, considering that 8 blocks would have given me 400 coins solo, obtaining only 328 from the pool means unlucky to me.

My hash rate is around 340125 khash/sec, this is my plunge:

Erm, I don't understand your point here.  Hacim is saying that he's found 8 blocks, which without the pool would have gained him 400 BTC, while because he did it for the pool he only has 328 BTC to show for it, which is a net loss.  The "more blocks than the average person would" is based on hashrate, which Hacim did not mention.

Dang, no wonder. Good luck with that, slush. Are you just writing your own GetWork, or are you creating your own transactions for payout as well? What would be kind of cool is if you created the generation transaction with multiple outputs, if that's possible. That way everybody gets newly minted coins.

Unlucky? Surely this means you are rather lucky - you have found more blocks than the average person would. But the pool averages it out.

As for the 7-day average - it goes down as the difficulty goes up, due to more people crunching the numbers.

I decided to completely rewrite the pool core and avoid using standard bitcoin client. This is quite big project and I don't see it's finish yet. So no, I currently don't have an idea when the new pool will be up.

slush, any idea when registrations will be reopened?

As slush said, the difficulty has increased by 40% and then another 55% in the past 20ish days.

TLD is .cz, but server is really located in London.


Difficulty?

I am also quite unlucky. I've found 8 blocks for the pool, but my balance is just 328. I've also noticed my 7-day average go down quite a bit since Feburary 8th for reasons I cannot understand.
